BUNDLING-PRESS.

Specification of Letters Patent.

Application filed April 29, 1905- Serial Nv 258,035-

To all whom it may concern:

Be it known that we, TALBOT C. DEXTER and CHARLES O. L. CARDELL, citizens of the United States, residing at Pearl River, in the county of Rockland and State of New York, have invented certain new and useful Improvements in BundlingPresses, of which the following is a specification.

Our invention relates to bundling-presses, and is more especially concerned with manually-operated bundling-presses.

One object of our invention is to provide a hand-power bundling-press for compressing into compact form bundles of signatures which are to be stored.

Another object of our invention is to provide a hand-power bundling-press in which a maximum amount of power is obtained and which will take up a minimum amount of ace.

A still further object of our invention is to provide means for adjusting the machine to suit bundles of different-sized signatures. This object is accomplished by the invertible arrangement of the compression-heads.

Many features of novelty will be seen from the description of our invention in detail with reference to the accompanying drawings, and these will be more particularly pointed out in the annexed claims.

In the drawings like reference-numerals are used to indicate the same parts in the various views.

In said drawings, Figure 1 is a side elevation of the complete machine. Fig. 2 is an end elevation of the same. Fig. 3 is a top plan view of the same. Fig. 4 is a detail view of one side of the carriage which carries the movable head and its operating mechanism. Fig. 5 is a back view of one of the heads. Fig. 6 is a side view of the same. Fig. 7 is a face view of the same, and Fig. 8 is a diagrammatic representation of one of the heads, showing the eccentric arrangement of the grooves.

Referring now more particularly to said drawings, 10 is the front frame, and 11 the rear frame, of the machine. 12 designates a pair of bars securing the front and rear frames together near the base.

An intermediate shaft 27 transversely in carriage 17 and has sphned to bars. It will be understood that the rackbars 13 and the trough-bars 14 together form the trough in which the bundle of signatures about to be compressed is placed.

15 and 16 indicate the front and rearheads, respectively, which are removably positioned in the trough, the front head 15 being secured to the carriage 17, which is adapted to be moved along the trough through mechanism which will be hereinafter described. The rear head 16 is removably secured to a support 18 upon the rear frame 11. The car riage 17 is formed in two complementary parts, one of these parts being represented m detail in Fig. 1. Each half of said carriage has a collar 19, which fits around the rack-bar 13 and is provided with a recessed portion 20 for a purpose hereinafter set forth. A plate 21 is provided at one end of the carriage, which has a cut-away portion 22, which registers with a similar portion on a similar plate on the other half of the carriage and forms together with it a slot through which the set-screw 23 of the front head 15 passes for detachably securing the front head 15 to the carriage 17. In addition to the collar 19 ,each half of the carriage is provided with a pair of bearing-sleeves24 and 25, which, together with the corresponding parts of the other half of the carriage, receive the shafts 26 and 27, respectively. (See Figs. 1, 2, and 3.)

A shaft 26 is journaled transversely in the carriage 17, as shown in Fig. 3, and carries a hand-wheel 28, a ratchet-wheel 29, and a pinion 30, all of which are fixed to sa1d shaft. is also journaled it a gear-wheel 31, which is in mesh with the pinion 30, and a pair of spur gears 32, which are in mesh with the racks of the rack-bars 13. (See Fig. 1.) The spur-gears 32 are positioned in the recessed portions 20 of the collar 19. By reason of the arrangement of shaft 26 transversely upon the carriage 17 it will be observed that the hand-wheel28 is supported to rotate in a vertical'plane parallel with the direction of travel of the car riage, thereby affording a most convenient and effective arrangement for the operator,

cure the front and rear frames together near the top, and 14 indicates a pair of trough- A bracket 33 is provided on that half of the carriage which is shown in Fig. 4 and has a pair of ears 34 and Pivoted to this bracket is a pawl 36, which engages in the ratchet-wheel 29 for holding the pressing mechanism under pressure. For raising this detent out of engagement with the ratchetwheel we also pivot to the bracket 33 an operating-lever 37, which has a downwardlyextending member 38, provided with a pin 39 for lifting the pawl 36 when the lever is rocked and a weighted upwardly-extended arm 40, which is adapted to be held in either position to which it may be set by the ears 34 and 35.

The compression-heads 15 and 16 are each provided in their working faces with a pair of grooves 41 and 42, which extend from a pair of tubular recesses 43 and 44. As diagrammatically shown in Fig. 8, these grooves do not intersect each other at the center of the working face of the compression-head, but are purposely arranged to intersect at a point above the center, so thatby inverting the heads in the trough the point of intersection may be varied to allow for different-sized signatures. It will be observed that the compression-heads'15 and 16 are of rectangular shape. The described arrangement of intersecting grooves 41 and 42 is produced by forming the said grooves in such positions in the working faces of the compression-heads that each groove will extend between and parallel with two opposite edges of the working face and at unequal distances from said edges-that is, each groove will be nearer one edge of the working face than the opposite edge of said working face. The tubular recesses 43 and 44 are made large enough for the attendant to insert his hand for wrapping and tying the cord around the bundle which has been compressed.

It is obvious that in the operation of our improved hand-power bundling-press upon turning the hand-wheel 28 the carriage 17 will travel along the trough, carrying the operating mechanism and the front compression-head bodily along with it. By doing away with the moving rack-bar we avoid the taking up of unnecessary space by the rackbar protruding beyond the normal length of the machine when the compression-heads are in the extreme position. When the bundle between the compression-heads 15 and 16 has been pressed by this operation to sufficient compactness, the pressing operation may be discontinued, and the detent 36 by its engagement with the ratchet-wheel 29 will hold the compression-heads under pressure, while the attendant may then turn his attention toward wrapping cord around the bundles and tying them up. Upon the completion of this the lever 37 is rocked, whereby the pawl 36 is caused to disengage the ratchetwheel 29 and the pressure is then taken off.

We are aware that compression-heads in bundling-machines have been provided with a double series of parallel grooves on the working face for the passage of the tyingcord, one series of grooves being at right angles to the other, so that by the use of a long needle the cord may be passed around the bundle at a chosen height above the bottom of the trough but it has never before been proposed, to our knowledge, to employ invertible heads with a pair of slots crossing on a diagonal line at a point unequally distant from the diagonally opposite corners of the face and having within the body of the head and communicating with said slots enlarged cavities for the passage of the hand in tying.

Having thus described our invention, what we claim as new therein, and desire to secure by Letters Patent, is
